INTRODUCTION The course and prognosis of vitreous hemorrhage (VH) are difficult to predict in spite of so far published experimental and clinical studies. OBJECTIVE The goal of this study was to follow the course and evaluate prognosis of vitreous hemorrhage. METHODS The experiment was performed on 19 Chinchilla rabbits (Oryctolagus cuniculus), both males and females (38 eyes), weighing 250...

INTRODUCTION Vitreous or retinal hemorrhage occurring in association with subarachnoid hemorrhage is known as Terson's syndrome. In Terson's syndrome, intracranial hemorrhages are followed by intraocular hemorrhage, classically in the subhyaloid space, but may also include subretinal, retinal, preretinal, and vitreal collections. Vitreous hemorrhage recovery is usually spontaneous in six to 12 ...

PURPOSE This study aimed to evaluate the benefits of Nd:YAG laser posterior hyaloidotomy as a method allowing rapid drainage of subhyaloid hemorrhage into the vitreous gel. DESIGN Nonrandomized, prospective, interventional, controlled case series. METHODS Nd:YAG laser posterior hyaloidotomy was performed in four eyes of three patients with premacular subhyaloid hemorrhage. The etiologies we...

SEPTEMBER 2010 I RETINA TODAY I 71 C onventional vitreoretinal surgery uses three pars plana sclerotomies.1 During the procedure vitreous gel is removed and the intraocular volume is replaced for balanced salt solution perfusion.2 Perfluorocarbon liquids consist of a hydrocarbon molecule in which hydrogen atoms are replaced by fluorine atoms. Since 1987, Chang et al3 have recommended the use of...

PURPOSE To present our findings on the cause of an acute visual field defect (VFD) that developed in a patient on the day after vitrectomy for proliferative diabetic retinopathy. CASE A 50-year-old man complained of a blind area in the superior visual field that developed one day after vitrectomy. The patient had undergone uncomplicated vitrectomy for a long-duration vitreous hemorrhage assoc...

BACKGROUND We report on a patient with proliferative diabetic retinopathy (PDR) and human immunodeficiency virus (HIV) infection who exhibited extremely active PDR followed by a rapid onset of blindness in the right eye. The progression of visual disturbance in the patient's left eye was slowed after starting highly active anti-retroviral therapy (HAART), and vision in that eye was rescued afte...

T R E ATM E N T O F PD R In 2005, after our initial encouraging experience with intravitreal bevacizumab for age-related macular degeneration, I began to use it in patients with rubeosis. The first patient I treated presented with bilateral neovascularization, rubeosis in the right eye, and partial vitreous hemorrhage in the left eye.1 I applied panretinal photocoagulation (PRP) for the left ey...

Aim: The purpose of this study was to evaluate the efficacy and safety complications following combined pars plana vitrectomy phacoemulsification surgery eyes for management vitreous hemorrhage due proliferative diabetic retinopathy as well pronounced cataracts.
 Material Method: Phacoemulsification 23G procedures were performed cataracts. Age, gender, best-corrected visual acuity before a...

PURPOSE To measure the levels of interleukins (IL) 1 beta, 6, and 8, and tumor necrosis factor-alpha (TNF alpha) in the vitreous of patients with proliferative vitreoretinopathy (PVR), proliferative diabetic retinopathy (PDR), vitreous hemorrhage, and macular pucker. METHODS Vitreous samples were collected, undiluted, from patients with PVR, PDR of varying severity, and miscellaneous lesions ...
